Chemical agents and hydraulic oil may be present... Our company's couplings might be usable even in that environment!

Generally, when selecting a joker coupling made of polyurethane resin, it is necessary to verify the compatibility of the type of operating oil that may scatter and the chemical substances with the resin components. Attached is the oil resistance list included in our catalog. Standard ROTEX spiders do not have resistance to phosphate ester-based operating oils or chlorinated hydrocarbon-based operating oils. In such cases, solutions using high chemical resistance polyamide resin, such as the following, are effective: - BoWex M: A gear coupling made of metal and resin using a polyamide sleeve. - Changing the ROTEX spider to polyamide material or PEEK material. Both are types and series that KTR specializes in. For more details, please refer to the catalog download or contact our office!
